Generate and validate ISO 20022 Exceptions & Investigations (E&I) `camt` messages — with an [MCP][mcp] server. Starts with `camt.056` (FI-to-FI Payment Cancellation Request): the message a bank sends to recall or cancel a payment it already dispatched — a duplicate, an erroneous amount, a fraud recall. Output is validated against the official bundled XSD before it's returned.
Latest release: v0.0.20:camt.056+camt.029generation + validation, 4 MCP tools over stdio, streamable HTTP or SSE, 100% branch coverage, for Python 3.10+. Part of the ISO 20022 MCP suite. Additional E&I messages (camt.029, camt.026, camt.027, camt.087) plug into the same engine.
Why E&I
When a payment goes wrong, the fix is an Exceptions & Investigations message — and these
